Abstract (en)
[origin: WO2020223186A1] A power tool is provided with a coating to distribute static electricity away from the surface of the handle of the tool. The tool includes a handle configured to be grasped by a user. The handle includes a surface and a first material having a first surface resistivity. The tool includes a coating covering at least a portion of the handle. The coating is configured to distribute static electricity away from the surface. The coating is made of a second material having a second surface resistivity less than the first surface resistivity.
